You are considering using IPMP and Link Aggregation. Which two statements are true about these
technologies?
A.
IPMP requires all interfaces to support the same bit rate.
B.
Both technologies can increase outbound bandwidth.
C.
Link Aggregation does not offer link failure protection.
D.
Link Aggregation requires all interfaces to support the same bit rate.
E.
IPMP supports load spreading across all interfaces for inbound traffic
Explanation:
Explanation/Reference:B: Link aggregations provide high availability and higher throughput by aggregating multiple interfaces at the
MAC layer. IP Multipathing (IPMP) provides features such as higher availability at the IP layer. Both IPMP and
Link Aggregation are based on the grouping of network interfaces, and some of their features overlap, such as
higher availability. These technologies are however implemented at different layers of the stack, and have
different strengths and weaknesses.
E: Internet Protocol Network Multipathing (IPMP) provides fault-tolerance and load balancing across multiple
network interface cards. By using IPMP, you can configure one or more interfaces into an IP multipathing
group. After configuring IPMP, the system automatically monitors the interfaces in the IPMP group for failure. If
an interface in the group fails or is removed for maintenance, IPMP automatically migrates, or fails over, the
failed interface’s IP addresses
Incorrect:
Not A: The same (non-null) character string IPMP group name identifies all interfaces in the group. You can
place interfaces from NICs of different speeds within the same IPMP group, as long as the NICs are of the
same type.
Not C:If LACP (Link Aggregation Control Protocol) cannot aggregate all the ports that are compatible (for
example, the remote system might have more restrictive hardware limitations), then all the ports that cannot be
actively included in the channel are put in hot standby state and are used only if one of the channeled ports
fails.
Not D: MP is built into Oracle Solaris and does not require any special hardware. Any interface that is supported
by Oracle Solaris can be used with IPMP. However, IPMP does impose the following requirements on your
network configuration and topology:
/All interfaces in an IPMP group must have unique MAC addresses.
/ All interfaces in an IPMP group must be of the same media type.
/ All interfaces in an IPMP group must be on the same IP link
